First, high Contrast
Contrast is one of the key factors that affect the visual effect, the higher the contrast, the clearer the image and the more vivid the color. High contrast is very helpful to image clarity, detail performance and gray level performance. In some black and white contrast of the larger text, video display, high contrast full-color LED display in black and white contrast, clarity, integrity and other aspects have advantages. Contrast for the dynamic video display effect to be greater, because the dynamic image of the light and shade conversion is faster, the higher the contrast, the more easily people's eyes to distinguish the conversion process. In fact, the contrast of Full-color LED display is mainly to improve the brightness of full-color LED display and reduce the surface reflectivity of the screen, however, the brightness is not the higher the better, too high, but will backfire, light pollution has become a hot topic now, the brightness of the environment and the impact of the crowd. Full-color LED display LED panel and led light-emitting tube for special process processing, can reduce the LED panel reflectivity, but also to improve the full color LED display contrast.
Second, high gray level
Gray level refers to Full-color LED display single color brightness from the darkest to the brightest between the brightness series, Full-color LED display of the higher gray level, the richer the color, the more gorgeous color; The increase of gray level, can greatly enhance the color depth, so that the display level of the image color increase in geometry. LED grayscale control level is 14bit~16bit, so that high-end display product image level resolution details and display effect reached the world's advanced level. With the development of hardware technology, led gray level will continue to higher control precision development.
Three, small spacing products
Reduce the total color LED display point spacing, can be very good to improve its clarity, Full-color LED display point spacing smaller, the more delicate the screen display. But the production of full-color LED display Price is also high, but fortunately now the market is also moving towards small spacing LED display development.
